Description of two new species of Enclisis (Hymenoptera: Ichneumonidae) and support for the secretory role of tyloids in ichneumonid males

Abstract

Two new species of Enclisis Townes, 1970 from Spain are described and illustrated: E. dichroma sp.n. and E. schwarzi sp.n. The new species are distinguished from the closest species E. infernator and E. ornaticeps by head and leg characters and body colour. Data on their phenology and a key to these four European species are presented. External and internal scanning electron microscopy of male tyloids revealed that these structures, in both new species, have a secretory role.
